Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Core-shell Li2TiO3-Li4SiO4 has been suggested as an advanced tritium breeder for outstanding mechanical strength and rich lithium. However, no study has reported on the release behavior of hydrogen isotopes from core-shell Li2TiO3-Li4SiO4. This paper focuses on a deuterium exposure experiment to investigate deuterium release behavior. X-ray diffraction, Raman, and electron spin resonance measurements were adopted to analyze the phase change, crystal structure modification, and defects before and after deuterium exposure. Thermal desorption spectroscopy was used to study the deuterium release behavior of core-shell Li2TiO3-Li4SiO4. Deuterium release from single Li4SiO4 and Li2TiO3 was also examined for comparison. The similarity of the deuterium release profiles between core-shell Li2TiO3-Li4SiO4 and Li4SiO4 was observed, which was considered to be caused by the incomplete coverage of shell Li2TiO3 on the core-shell samples.
